Kubernetes

Why I like it

Standard behavior and operations regardless of cloud provider (Azure, GCP, Baremetal)
Smart by default
Right tool (borg) by the right people (google) at the right time (right after docker).

Favorite Command

kubectl exec -it shell-demo -- /bin/bash

kubectl apply is up there but this guy lets you run a bash terminal on a running pod. This is great for investigating local files or anything else you didn't think of preparing for originally within the container.

Shout out to https://www.jeffgeerling.com/blog/2018/updating-kubernetes-deployment-and-waiting-it-roll-out-shell-script for an excellent replacement for kubectl wait.
